泉州双环 小李
油封，又称为旋转轴唇形密封圈，英文为OIL SEALS、LIP SEALS、SHAFT SEALS。油封主要是用于防止润滑油或其它液体从其旋转轴和箱体间泄漏以及尘埃或沙土从外部侵入。油封的密封作用，就是密封唇与轴直接接触，在油侧和空气侧之间形成一层薄成稳定的油膜，阻止油的泄漏。如果油膜过厚，则会产生轴向流动面泄漏；如果油膜太少，则橡胶唇与轴之间干摩擦而产生磨损，使密封失效。
骨架油封是油封的典型代表，一般说的油封即指的是骨架油封。油封的作用一般就是将传动部件中需要润滑的部件与出力部件隔离，不至于让润滑油渗漏。骨架就如同混凝土构件里面的钢筋，起到加强的作用，并使油封能保持形状及张力。按结构形式可分单唇骨架油封和双唇骨架油封。双唇骨架油封的副唇起防尘作用，防止外界的灰尘，杂质等进入机器内部。按骨架型式可分为内包骨架油封，外露骨架油封和装配式油封。按工作条件可分为旋转骨架油封和往返式骨架油封。用于****发动机曲轴，****发动机曲轴，变速箱，差速器，减震器，发动机，车桥等部位。
1、NATIONAL油封的发展历程
NATIONAL OIL SEALS是1920年由LIoyd A.Johnson创立的，专门从事油封、
垫圈垫片的生产，在当时就已经是美国zui大的油封生产厂家之一，为汽车和飞
机的主要配套油封工厂。于1956年被Federal-Mogul揽于旗下。F-M公司是一家
综合性的汽车零配件厂家，从1899年成立至今，通过不断的发展和并购，拥有
了一系列的汽车零部件品牌，产品包括轴瓦、引擎、雨刷、火花塞、轴承、油
封、活塞环、制动系统、垫圈和底盘系统等等，成为了的汽车零部件
供应商。
2、NATIONAL油封的制造基地
NATIONAL油封制造基地从刚创立时的San Francisco， 至1942年搬到
Redwood City，再后搬至Summerton和Mexico City，现已把制造重心放在了
MEXICO CITY。这就是为什么油封上会标注为USA和MX的缘故。除此两处之外，
NATIONAL油封再也没有其它的制造基地了。
3、NATIONAL油封的常用型式
NATIONAL油封在中国市场上常见的型式如左所示的截面图。油封分内包骨架油
封和外露骨架油封，带自紧弹簧式和无自紧弹簧式。但NATIONAL油封zui主要以
外露骨架为主，常用的有41、45、47、48系列。外骨架油封相对于内骨架油封
来言，刚性好、定位准确、同轴度高、导热散热好、加工精度高、要求胶与金
属之间有较高的粘合强度。
4、NATIONAL油封的特征
NATIONAL油封与其它品牌的zui大不同之处，就是在铁壳外圈的外径上喷涂了红
色的REDICOAT涂漆，一方面可以区别其它品牌的颜色，另一方面，也是zui
主要的方面，铁壳外径喷涂红漆可增加外径的密封性能，可填充装配孔腔表面
之缺陷或刮痕，避免密封流体由外径泄漏。这种REDICOAT涂漆，对孔腔面的加
工光洁度就有所放松，允许有较大的表面粗糙度，同样起到内骨架油封（外径
包有橡胶）的密封效果。
zui能体现NATIONAL油封技术含量的是37系列和38系列，这两个系列是车轴轮端油封，称为组合油浴式油封或自转式油封。这种型式的油封是由一个铁壳油封和一个凹形耐磨套筒组合而成，油封的密封唇旋转在衬套面上，不直接与轴接触，可避免轴被油封唇部磨耗而产生沟槽，从而保持了轴心，在下次维护时不须重新研磨轴的表面而进行更换油封；另一方面，密封唇包裹在凹形的衬套内，又可以避免密封唇与外部脏物接触而造成阻塞失效。在密封性能方面，这两种系列油封在内径与外径面涂上了橡胶层，密实地贴在轴和孔壁上。
38系列不同于37系列在于，38系列的油封是由技术含量更高的填充聚四氟乙烯PTFE复合材料组成，这种技术是NATIONAL油封公司在上世纪80年代研发出来，用来代替唇形橡胶油封，成功解决了橡胶骨架油封因材质本身问题造成的漏水、漏油问题。成功地解决了发动机漏水、漏油问题,同时大大提高了发动机乃至汽车的技术性能。 PTFE油封的抗磨擦性,特别适用于无油或少油状态工作，即使*停机后再度启用,也能立即拥有低磨擦特性，橡胶油封仅适合有油状态工作。NATIONAL油封38系列，可用于的温度，可用于混合润滑剂之中。的LAY-DOWN双重PTFE密封唇，可提供更大的密封面积，尤其在轴振摆大的场合。油封的结构上，设置了四重防污染系统，保证了*的排污性能。
